Phase 1 : endpoints API complets

- CoastalPoint → shortName Spot → /api/spots (API Platform)
- SargassumForecast → shortName Forecast → /api/forecasts
- ObservationController : GET /api/observations avec filtres
  bbox (PostGIS ST_Intersects), date, source + geometry ST_AsGeoJSON
- SpotScoreController : GET /api/spots/{id}/score avec ?at= optionnel
- FeedbackController : POST /api/feedback, anonyme, fingerprint SHA256
- CORS : autorisation radarsargasses971.com + localhost dev
